基于灰色白化权函数聚类法的木结构古建筑安全性评估

Safety Assessment of Timber Ancient Buildings Based on Grey Clustering Analytical Method

为了评价木结构古建筑的安全性等级,提出了一种基于灰色白化权函数聚类法的木结构古建筑安全性评估方法.运用此方法分析了灵水村114号院南房的安全性,首先运用层次分析方法(AHP)确定各指标子因素的权重,再采用灰色白化权函数聚类法进行聚类分析,按灰色聚类系数最大值原则确定结构的安全性等级及隶属度.结果表明:利用灰色白化权函数聚类法得到的木结构古建筑安全性等级与检测结果相同.

mTo evaluate the safety level of the timber ancient buildings, grey whitenization weight function clustering method of timber ancient buildings was proposed in this paper. The safety of southern room, No114, Iingshui village was analyzed by the method. Firstly, different weight of sub-factors of each index was determined by using analytic hierarchy process （AHP）. Then cluster analysis was made by grey whitenization weight function clustering method. Furthermore, safety level and subordination degree of timber building was confirmed according to the principle of the maximum of grey clustering coefficient. The results show that the safety level of the timber ancient buildings obtained by grey whitenization weight function clustering method has good agreement with testing result.
